MDEV_ID_VHOST isn't used yet here. Also, given the strong
interdependence between the class_id and the ops structure, we might
wand to define them in the same place. Thanks,

Rethink about this, I believe it's better to define the device ops in
their own headers, and one set of device ops could be used for two
classes (e.g both virtio and vhost). And to avoid a duplicated ID
definition. I tend to keep this in the common mdev.h header.
Thanks
